Mini-Drupal Database backup and a large site MySQL backup strategy tutorial

Small and medium site simple backup policy

The small and Medium line Web site based on Drupal, we can use the Backup_migrate module, which provides the function of regular backups, the time of backup, how many backups to keep, and so on, Once you've set it up, you can backup successfully by performing Cron regularly. The General Drupal Station, we only need to use SVN can, on the server side, we put back the good data to SVN, we can achieve the purpose of the backup. Because Drupal's backup module can set up the number of copies that are reserved for backups, it does not cause too many backup files, resulting in svn being large.

The following is a simple backup script, placed in the root directory of the site, and then added to the crontab daily execution.

The code is as follows	Copy Code
#!/bin/bash Date #start Date drush_php=/bin/php #php Path Export drush_php Drush Cron SVN St sites/default/files/backup_migrate/scheduled/| grep ' ^! ' | awk ' {print $} ' | Xargs SVN Delete--force SVN add sites/default/files/backup_migrate/scheduled/* SVN ci sites/default/files/backup_migrate/scheduled/-m ' Add backup Files ' Date #end Date

The crontab settings are as follows

The code is as follows	Copy Code
0 0 * * * cd/www/web/html/&& bash cron.sh > Cron.log 2>&1

MySQL backup strategy for large site

If the database is slightly larger site, using SVN temporary backup is slightly thin, then need to use the MySQL backup strategy, we need to backup the entire database compression, and then periodically transferred to the backup database or to other cloud servers, here a simple PHP sample code.

The code is as follows

Copy Code

#!/usr/bin/php-q <?php $to = "gaoxinzhao@gmail.com"; $hostname = EXEC ('/bin/hostname '); $MYCNF = "/HOME/ROBBIN/.MY.CNF"; $ignore = Array (' Information_schema ', ' Test ', ' MySQL ', ' wdcpdb '); function TRIMW ($STR) { $str = Str_replace (Array ("n", "R", "T", "", "O", "Xob"), "", $str); return $str; } if (!file_exists ($MYCNF)) { Mail ($to, "No. MY.CNF exists on $hostname", "MySQL cannot dump because. my.cnf are missing on $hostname.") ; Exit ("Cant get user creds"); } $myconf = file_get_contents ($mycnf) or Die ("Failed to open bmesh_admin '. my.cnf"); Preg_match ("/buser (. *)/", $myconf, $matches) or Die (mail ($to, "No username in. my.cnf on $hostname", "MySQL cannot dump On $hostname ")); $USR = (explode (' = ', $matches [0])); $user = TRIMW ($usr [1]); Preg_match ("/bpassword (. *)/", $myconf, $matches) or Die (mail ($to, "No password in. my.cnf on $hostname", "MySQL cannot Dump on $hostname ")); $pass = (explode (' = ', $matches [0])); $password = TRIMW ($pass [1]); mysql_connect ("localhost", $user, $password) or die ("Could not connect:". Mysql_error ()); mysql_select_db ("MySQL"); $result = mysql_query ("show Databases"); $bpath = "/home/robbin/backup/mysql"; $btime = Date ("y-m-d h:i:s"); $bstamp = Strtotime ($btime); $byear = Date ("Y", $bstamp); $bmonth = Date ("M", $bstamp); $bday = Date ("D", $bstamp); $btod = Date ("H-i-s", $bstamp); while ($res = Mysql_fetch_array ($result)) { $myDb = $res ["Database"]; if (In_array ($myDb, $ignore)) continue; $mdir = "$bpath/$byear/$bmonth/$bday/$btod/$myDb"; $out = ' mkdir-p $mdir '; $myFile = $myDb. ". SQL"; $BLDCMD = "CD $mdir;"; $bldCmd. = "Mysqldump-u$user-p$password--single-transaction--add-drop-table-r-c-q $myDb > $myFile;"; $bldCmd. = "chmod 644 $myFile;"; $bldCmd. = "Chown root:root $myFile;"; $bldCmd. = "Gzip-9 $myFile"; Print "Backing up $myDbn"; Print "Securing $myDbn"; $out = ' $BLDCMD '; } $out = ' chmod $bpath/$byear '; print "$outn"; Print "Backups are in $bpathn";

Settings for Crontab

The code is as follows	Copy Code
0 1 * * */home/robbin/bin/mysql_backup.php

In addition, we need to transfer the backed-up data to other servers on a regular basis to prevent the server from crashing and causing data loss. Backup timely site only to ensure that this is just the author of a little bit of operation to share, we have a better backup strategy, welcome to share.
